spiderkeeper 部署&操作

环境配置

由于 scrapyd是基于python3+以上的版本兼容性较好,所以我们需要的环境为

python3.4+
scrapyd
scrapy & scrapy相关的库
scrapy_reids 如果缺少这个在部署任务会报错 (Reids.KeyErroe:'xxx'), xxx我们部署的任务.
SpiderKeeper `pip install spiderkeeper' 就可以安装.
启动&配置
安装完成之后,便可以启动服务器了.博主本人使用的是ubuntu,所以就以ubuntu为例,win&macos进本一样.

单台服务器

sudo spiderkeeper   
# 启动单台服务器,默认启动本地的 http://localhost:6800 scrapyd的服务 | spiderkeeper的默认端口为5000.
连接多台scrapyd服务器.

在分布式中我们的服务器中肯定不止一台,使用spiderkeeper可以很好的解决这个问题

sudo spiderkeeper --server=http://localhost:6800 --server=http://111.111.111.111:6800 
 #启动一个spiderkeeper可以同时部署两台服务器的spider

更改用户名&密码&更改端口号

config.py 更改用户名&密码

# spider services

# basic auth 这里更改用户名&密码

run.py更改端口号
